Christian Slater became the poster child of angst-ridden, outsider teens by starring as mobilizing rebels in “Heathers” (1989) and “Pump Up the Volume” (1990), both of which painted a dark portrait of high school hierarchy. Slater’s screen persona as a handsome and insightful but gun-toting scofflaw – complete with Jack Nicholson mannerisms – played out well in films like “True Romance” (1993), but by then it was glaringly apparent that Slater’s “act” was no act. He segued into adult roles with moody dramas like “Interview with a Vampire” (1994) but repeated arrests and multiple trips to rehab made directors leery. After a downward slide that deposited the actor in direct-to-video horror films, a sober Slater began earning back his once-promising reputation with acclaimed stage roles on London’s West End and on Broadway. In his first primetime series “My Own Worst Enemy” (NBC, 2008-), Slater was well cast as an intelligence officer unwittingly leading two drastically different lives. Slater’s restless personal life may have robbed him of a sturdier career as a big screen leading man, but when the actor finally quieted his demons, his on-screen appeal remained intact and his dramatic skills were inarguably stronger than ever.
